The modern dietary regimen known as the Paleolithic diet (abbreviated paleo diet or paleodiet), also popularly referred to as the caveman diet, Stone Age diet and hunter-gatherer diet, is a nutritional plan based on the presumed ancient diet of wild plants and animals that various human species habitually consumed during the Paleolithic—a period of about 2.5 million years duration that ended around 10,000 years ago with the development of agriculture. In common usage, such terms as the “Paleolithic diet” also refer to the actual ancestral human diet.[1][2] Centered on commonly available modern foods, the “contemporary” Paleolithic diet consists mainly of meat, fish, vegetables, fruit, roots, and nuts, and excludes grains, legumes, dairy products, salt, refined sugar, and processed oils.
